We will continue our organized approach to diagnosing a pool heating system by looking at just what to do when the light in the control pad on the best of your Sta-Rite swimming pool and spa heating system that is labeled “solution heating unit” is lit. (We will certainly click here proceed with the assumption that you recognize everything from section one.) This moment you will certainly have to get rid of the sides from the heating system prior to separating power to the heating unit so that you could read the codes on the board affixed to the topside. After taking out the sides, you will certainly view the huge topside that is still connected to the heater. Here the topside is a metal panel that keeps the topside in position. Under this panel there are 2 securing pins (cotter pins). Meticulously remove the two pins and also save them somewhere protected till reassembly. Carefully get rid of the peak and transform it upside down. You will see a light lit on the board you are looking at when you transform the topside over. The light will certainly be beside a code that is created on the board.

The first code that you'll view on the left side of the board will certainly be PS. This is the code for the stress switch. We covered the pressure switch in sector one. If this light is lit go back to section one and assess that section. If needed comply with the directions to change the tension switch.

The following code you'll see on the board is HLS. If you have a controller on the system you will need to bypass it currently. You will certainly should very carefully detach the power from the heater. After you are sure that the power is separated, you will certainly need to locate and also open the high-voltage cupboard. This closet is a steel box in the center of the heating system. If you are checking out the cabinet, there is usually a screw on the top right side. Release the screw as well as the door will certainly turn down towards you. You should be remarkably cautious when operating in this box and also simply do so when you make sure that the power to the heater gets out.

You will should bypass the firewall software security user interface. To do this you will certainly need a brief cord with stab-tab adapters. If you have a controller as well as it was appropriately mounted the wire might have been left in the box by the tech who installed the controller. If not you will should make this jumper wire. At this factor look in your owner's handbook to locate both appropriate pins to link to. If you have a controller or are utilizing a fireman's switch this is where your control must be connected. If you have a controller as well as it is not connected right here, it could be the source of your issues and also either have a certified tech deal with the trouble or correct it yourself.

You should make sure not to put the jumper cord on the power terminals or you will damage your heating unit by burning up the electronic device. Use your manual to situate where the fire fighter's switch is supposed to be affixed and also carefully connect your jumper between these terminals. If you now turn on the power as well as the heating system works with no troubles, your problem depends on the controller or the electrical wiring going to the controller. You will need to trouble shoot this technology.

If you still have the very same problem with your heating system. (“service heating unit” light comes on), leave the jumper in place as well as validate that the pump is on and that you have excellent water flow. See to it once more with your meter that the stress switch is not cycling. It needs to review as a dead short. (View section one) With excellent water flow confirmed and the “service heater” light on, your issue can be one of the thermo-regulators in the safety and security technology.

Since we started this with the indication light on the board lit next to HLS, the very first point we are going to inspect are the cables going to the high limitation button. The high restriction button is found near all-time low on the left side of the water manifold as you admit. To see it you should remove the side cover on the water manifold. The screw that holds the cover is on the best of it. You should ensure that the orange wires going to the button are undamaged, attached and also not corroded. If the wiring is good, utilize your multi-meter to examine that the higher limit button reviews as a dead brief. If it reviews open as well as the water is not over 104 F, change the high limit button. If this does not fix your issue you might have a bad control panel and also it will certainly have to be switched out. Testing the control board is a very engaged procedure and also will be managed in a later sector.

This is the end of sector 2 and also has taken you via component of the safety and security circuit in the heater and 2 of the indicator lights on the board. We will certainly continue on with our organized diagnose of problems on the Sta-Rite swimming pool as well as spa heating unit in the following segment.
